Comb.

COMB APPLICATION FILED MAY 211 I917- Patented July 1?, 1917.

nip 5 COMB.

To all whom. it may concern:

Be it known that I, WILLIAM L. ANDER- soN, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Combs; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in combs and more particularly to that type of comb adapted for use in drying, straightening and smoothing the hair.

The primary object of the invention is to provide a comb of this character in which the pressure of the heated teeth on the strands of hair may be positively controlled by means of an adjusting screw.

Another object is to provide a device of this character formed from a heat conducting material adapted to retain the heat for a long period of time.

Another object is to provide a device of this character having movable teeth so arranged as to prevent catching and breaking off of the hair while operating the comb.

With these and numerous other objects in view, my invention resides in the novel features of construction and the combination and arrangement of the several parts as will be hereinafter described in they specification and claims and illustrated in the accom panying drawings in which:

Figure 1 is a side elevation of an improved comb;

Fig. 2 is a top plan View thereof;

Figs. 3 and 4 are longitudinal sections with parts in elevation showing two different positions of parts; and,

Fig. 5 is a detail transverse section on the plane of the line 5-5 of Fig. 3.

Similar reference numerals are employed to indicate corresponding parts throughout the several views.

The present embodiment of my invention as illustrated in the accompanying drawings comprises an elongated back 1 formed of any suitable heat conducting material and having a longitudinal recess 2 in its upper wall or face, said back being provided at its inner end with a suitable handle 8 and ferrule 4:. Formed integral with and depending from the lower wall or face 1 of the back is a plurality of parallel stationary teeth 5;.

Specification of Letters Patent. Application filed May 21, 1917.

Patented July 1'7, 1917.. Serial No. 170,020.

The recess 2 is provided in its bottom with a serles of openings which are disposed between the stationary teeth 5 for a purpose to be hereinafter set forth. The recess 2 is provided adjacent its inner end with a longi tudinal slot 6 which opens through the lower wall of the back 1, said slot being so disposed as to receive the short end 7 of an operating lever 8 which is fulcrumed adja cent its inner end between a pair of depend ing apertured ears 9, and whose purpose will be hereinafter set forth.

Disposed in the recess 2 is an elongated bar 10 having teeth 11 adapted to project through the openings between the stationary teeth 5, said bar and teeth being movable longitudinally of said back. The bar 10 is provided in its lower face adjacent its inner end with a transverse notch 12 which is adapted to receive the inner short end 7 of the operating lever 8. The outer end of the bar 10 is provided with a longitudinally extending threaded socket 13 which is alined with an aperture 14 in the outer end of the recess 2 and for a purpose to be set forth.

Upon pressing the lever 8 inwardly tos ward the handle 3, the short end 7 of the lever will force the bar 10 outwardly and thereby move the teeth 11 which are disposed between the stationary teeth 5 and for the purpose of returning the movable teeth to their former positions, a spring 15 which in this instance is in the form of an elongated flat strip, is adapted to have one end secured beneath the ferrule 4: and to have its other end contacting with the inner face of the lever 8, the tendency being to force the lever outwardly, thereby moving the teeth 11 inwardly. a

For the purpose of limiting the inward movement of the teeth 11 under the action of the spring 15, a set screw 16 is inserted in the aperture 1 1 in the end of the back 1 and is threaded into the socket 13 in the outer end of the movable bar 10. The aperture 14 is provided with a shoulder 14' which engages the head of the set screw to limit the inward movement thereof. It will be readily seen that the adjustment of the set screw will positively control the inward movement of the teeth 11, thereby controlling the pressure of the teeth upon the strands of hair.

In operation, the comb is heated by any suitable means and in drying, straightening or smoothing the hair, the set screw 16 is lllllll first adjusted and the lever 8 pressed inwardly to space apart the teeth and the comb is then placed in operative position, the strands of hair being disposed between the stationary and movable teeth and the lever is then released and is forced outwardly under the pressure of the spring 15. When the lever is pushed outwardly as above stated, the movable bar 10 will be shifted inwardly and the teeth will press against the strands of hair, and as the comb is drawn through the hair, said strands will be dried and straightened. It is readily seen that the set screw canbe adjusted to regulate the pressure of the teeth upon the hair so as to prevent breaking of the strands and at the same time thoroughly dry the same. 7 From the foregoing description, taken in connection with the accompanying draw ings, the construction and operation of my improved comb will be readily understood, but it is also to be understood that within the scope of the invention as claimed, numerous changes may bemade without sacrificing the principal advantages.

I claim 1.7 A comb of the class described including a back, a plurality of parallel stationary teeth on said back, a plurality of movable teeth'between said-stationary teeth, means for positively shifting said movable teeth in one direction, a spring for shifting said teeth in the opposite direction, and adjust able means for limiting the movement of said movable teeth by the spring.

2. A comb of the class described including a hollow back, a plurality of parallel stationary teeth on said back, a movable bar in said back, a plurality of movable teeth on said bar, said teeth being disposed be tween the stationary teeth, means for positively shifting said bar and movable teeth in one direction, a spring for shifting said teeth in the opposite direction, and an ad justable screw in said bar and engaged with saidback to limit the movement of said bar and the movable teeth by the spring.

3. A comb of the class described includback, a movable bar in said back, a plurality of parallel movable teeth between and coextensive with said stationary teeth, said movable teeth being formed integral with said bar, means for positively shifting said bar and movable teeth in one direction, a spring for shifting said bar and movable teeth in the opposite direction, and adjust able means for limiting the movement of said bar and movable teeth by the spring.

4. A comb of the class described comprising anelongated back having a longitudinal recess in its upper wall, a cover for said recess, a handle on the inner end of said back, a plurality of parallel stationary teeth. on the lower side of said back, said recess being provided with openings between said teeth, a movable bar in said recess, parallel and movable teeth on said bar, said movable teeth being disposed in said openings between the stationary teeth, said back being provided with a longitudinal aperture in its outer end, said bar having a threaded socket Valined with said aperture, said back having a longitudinal slot in its bottom near its inner end, a lever fulcrumed adjacent one end to said back and having its short end projecting through said slot, said bar having a transverse notch in its lower face adjacent its inner end to receive the short end of said lever, said lever being adapted to be pressed to shift the bars and movable teeth in one direction, a spring adapted to force the lever outwardly and shift the movable teeth in the opposite direction, and an adjustable set screw in said aperture and socket to limit the movement of said bar and movable teeth by the spring.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
